Using a GPS for tracking is extremely useful. I used my ForeRunner on this track to record what the track-layer did and then to run the track. The track was run semi-blind since I only knew the direction of travel and also that he was making a right-hand loop. Once we got into the woods, things became very hairy. Generally, I don't create a movie out of a track, but we spent a good hour running this track and I really wanted to go back and evaluate what happened. The movie is playing 120x speed and color indictes speed. We lost the GPS signal a bit at the very end so I chopped this movie off at that point.Zooey, did a great job and never got frustrated or lost concentration. Pretty much she was constantly looking for the track. In the places where the subject could walk a straight line, it was easy for her to be on track and move quickly. But most of the track was actually very difficult since the ground cover was boulders and thickets of mountain laurel drove how we moved.The track is about 4 or 5 hours old. We ran it at about 2PM and the temperature was in the 80s. First you see Chris laying the track. He placed flags at turns. Then you see Zooey and me run it. I was so happy to see the flags. At one turn, I had to let go of the line to crawl through some thickets and saw Zooey hanging out by the flags. Probably, the best moment of the day! Despite how bad it looks from this point-of-view, I was very pleased with how the dog performed.
